Steven Wu cdeef58e0f [Caching] Create clang importer from cc1 args directly ...

When caching build is enabled, teach dependency scanner to report
command-lines with `-direct-clang-cc1-module-build` so the later
compilation can instantiate clang importer with cc1 args directly. This
avoids running clang driver code, which might involve file system
lookups, which are the file deps that are not captured and might result
in different compilation mode.
